The present invention 10 discloses a training aid for golfers. The device 10 is designed to generate a collimated beam of red light 20 from a device 10 that is selectively attached to the brim 16 of a hat 18. Once attached to the hat 18, the golfer 12 positions their head to a desired point whereupon the light-emitting apparatus 14 is hingedly 24 adjusted to project the laser light onto the golf ball 22 thereby enabling the golfer 12 to easily ascertain whether there is unwanted head movement during the golf swing. The device 10 is comprised of a laser beam emitter 14 having an on/off switch 28 and a clip 26 for attaching the device to the brim of a hat and a hinge 24 positioned between the emitter and hat attachment means providing pivotal adjustment of the emitter.
